After ending LaGuerta's life, Deb is in a downward spiral, with the top cop drinking, using prescription drugs and hooking up with a trashy new love interest as she searches for a way to forget the fact that she murdered one of her mentors.

"Deb, look at yourself, you're lost," Dexter (Michael C. Hall) tells her. But the worst part for Dexter's foster-sister? After Deb is busted for a DUI, she wants to make a statement! About what? We'll just have to wait and see.
